Relax PBKDF2 iteration check for FIPS self-test
FIPS 140-3 IG 10.3.A.8 requires known-answer tests for KDFs. Some of these
tests for PBKDF2 use a low iteration count (e.g., 2) which is below the normal
security threshold and would otherwise fail.
This change checks if a PBKDF2 self-test is in progress and, if so, lowers the
minimum accepted iteration count to 2. This allows the required self-tests to
pass while maintaining the security check for normal operations.

The explicit `also_satisfies` list has been removed from the design. Instead
of manually listing which tests are satisfied by another, the new approach

We're getting a heap buffer overrun in the SRTP KDF.
Its caused by the fact that the fuzzer will occasionally generate salt
parameters that are very small, which passes the
OSSL_PARAM_get_octet_string function, but isn't long enough to be a
valid salt. Because of this, when we actually do the key derivation,
the SRTPKDF function assumes the salt is long enough and blindly
attempts to copy KDF_SRTP_SALT_LEN (14) bytes from the fetched parameter
into a local buffer, resulting in an overrun.
Fix it by checking the parameter length in the ctx_set_params method for
SRTPKDF, and if the octet string value is less than the required amount,
return an error to fail the ctx_set_params call.
While we're at it, based on review suggestions, also check that the
provided key parameter matches the requested cipher's expected key
length

add a compare thunk function to the STACK of macros
Now that ossl_bsearch is capable of using a thunking function, lets
create a thunking function to use for the STACK_OF macros.
The problem we're addressing is one that gives rise to ubsan issues.
clang-16 forward have a ubsan test that confirms that the target symbol
that we call through a pointer matches the type of the pointer itself.
for instance
int foo(void *a, void *b)
{
...
}
int (*fooptr)(char *ac, int *bc) = foo;
fooptr(&charval, &intval);
is strictly speaking in C undefined behavior (even though in normal
operation this works as expected). Newer compilers are strict about
this however, as several security frameworks operate with an expectation
that this constraint is met.
See https://github.com/openssl/openssl/issues/22896#issuecomment-1837266357
for details.
So we need to create a thunking function. The sole purpose of this
thunking function is to accept the "real" comparison function for the
STACK_OF macros, along with the two items to compare of the type that
they are passed as from the calling function, and do the convervsion of
both the comparison function and the data pointers to the types that the
real comparison function expects
So we:
1) Modify the DEFINE_STACK_OF macros to create this thunking function
2) Add an OPENSSL_sk_set_cmp_thunks api to set the comparison function
3) modify the requisite places in the stack code to use the thunking
function when available

It did not however enforce this, so a user could potentially
wrap something incorrectly without an error and then not be able to
unwrap it without an error. The code now checks that update is only

An internal function returned an int which could be negative for bad
input values, and the return value was assigned to a size_t which
ignored the error condition.

Make OPENSSL_cleanup() G A
(Your choice of G and A words)
This installs a global destructor if we have destructor support.
The global destructor does nothing and immediately returns under
normal operation. If a global flag indicating that global cleanup
is wanted, it does what OPENSSL_cleanup() used to do.
OPENSSL_cleanup() is then modified to set the global flag indicating
that global cleanup is wanted. At this point if we have destructor
support, it immeditely returns. If we do not have destructor support,
it manually calls the destructor function (meaning without destructor
support it does exactly what it used to do).
This ensures that if we have destructor support, the actions of an
OPENSSL_cleanup() requested by an application will only happen
after any subordinate library destructors which could call into
OpenSSL functions have already run.

Don't setup a default context while tearing down private contexts
In providers/applications that create custom libctx'es via
OSSL_LIB_CTX_new, its possible, if the default provider has never been

actually wind up creating the default libctx when we free the
aforementioned custom libctx via, as an example:
While this isn't catastrophic, its needless, and in some cases has the
potential to leak memory (for instance if a provider is loaded and
unloaded repeatedly in an environment in which the provider is linked to
libcrypto.so while the calling application is statically linked to
libcrypto.a
Its also fairly easy to clean up, by adding an internal parameter to

Implement second step of RFC7919 in TLS 1.2 server
Before this commit, the logic for generating a temporary DH key for DHE
cipher suites is the following:
1) If dh_tmp_auto is set (see SSL_set_dh_auto), the SSL server
automatically selects a set of DH parameters (P and G) appropriate
for the security level of the cipher suite. The groups are taken from
IKE (RFC 2409 and RFC 3526).
2) Otherwise, if the user provided a pre-generated set of DH parameters
(SSL_set0_tmp_dh_pkey), those parameters are used.
3) Finally, if neither 1) or 2) are applicable, a callback function can
be set using SSL_set_tmp_dh_callback, which will be invoked to
generate the temporary DH parameters. From OpenSSL 3.0, this
functionality is deprecated.
4) Using the parameters from step 1-3, an ephemeral DH key is
generated. The parameters and the public key are sent to the client.
The logic above is updated by inserting an additional step, prior to
step 1:
0) If tls1_shared_group returns any shared known group between the
server and the client, the DH parameters associated with this group
are selected.
This is still compliant with RFC7919, as the server will already have
checked the Supported Groups extension during the ciphersuite selection
process (implemented in the previous commit).
Now, the tests need to be updated: By default, the TLS 1.2 server will
default to RFC7919 groups. To bypass this behavior, the supported groups
on the client side is set to "xorgroup", ensuring that the client does
not advertise any FFDHE group support and the server falls back to the
old logic.
An additional test is also added to ensure that the TLS 1.2 server does
select the right group if the client advertises any of the RFC7919
groups.

RFC 7919 states:
If a compatible TLS server receives a Supported Groups extension from
a client that includes any FFDHE group (i.e., any codepoint between
256 and 511, inclusive, even if unknown to the server), and if none
of the client-proposed FFDHE groups are known and acceptable to the
server, then the server MUST NOT select an FFDHE cipher suite.
We implement this behavior by adding a new function that checks this
condition as its inverse: only select FFDHE cipher suites if at least
one of the client-proposed FFDHE groups is known and acceptable, or
if the client did _not_ send any FFDHE groups.
Also add a test to verify two possible outcomes:
1) The client proposes FFDHE and non-FFDHE ciphersuites -> the server
will select a non-FFDHE ciphersuite.
2) The client only proposes FFDHE ciphersuites -> the server will end
the connection.

Ensure current_crl always points to the crl we are considering
As mentioned by Viktor Dukhovni, the desired behaviour is:
The current_crl is NULL when the running callback invocation is about errors
unrelated to validation failures via a particular CRL a user may want to
report the issuer of.
The current_crl is (whenever possible) not NULL when reporting errors
specifically related to that CRL.
The problem with this happens when we call check_crl with something that
is not what current_crl is set to. We can potentially enter the time check
code, and we then need to call the callback with the certificate that
failed the time check which is not current_crl.
Correct this by removing the dance in the time check code, and always
setting current_crl whenver we call check_crl.
This means that when we are considering a delta crl, we report the
correct crl to the callback, instead of possibly handing them NULL
(if they get called after a failing time check clobbers it), or the
non-delta crl (because we are looking at a delta while having
current_crl set to crl - which was why we had the dance in the time code
to begin with. We don't need to change current_crl in the time check
code if we always have current_crl set to the thing we are evaluting.
